Is 156 a deficient number?

Here we will explain and calculate if 156 is a deficient number and its deficiency if applicable.

156 is a deficient number if the sum of its proper divisors is less than 156.

The sum of its proper divisors is calculated as follows: 1 + 2 + 3 + 4 + 6 + 12 + 13 + 26 + 39 + 52 + 78 = 236.

236 is not less than 156. Therefore, 156 is not a deficient number.

The deficiency of 156 is 156 minus the sum of its proper divisors. Thus, the deficiency of 156 is 156 - 236 = No Deficiency
